This is precisely why Zoom is acquiring Keybase. Zoom seeks to become the single "remote work tool", challenging Dropbox, et al. directly.

I'm particularly disenchanted with the growth of these multipurpose tools, but I am not their target audience. (Nor, I suspect, are many HN participants, but this is a baseless guess.) I suppose I'm more of an adherent to so-called "UNIX philosophy"--the best, single-purpose tool for each task, preferably that can be combined with its like for a solution customizable to how a specific user gets work done.
